DRYING AND HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent'No. 256,655, dated April18, 188 2.

I Application fi led January 30, 1882. (No model.) I

Be it known that I, AUGUSTE DREYFUS, a, citizen of Germany, residing at()atford, in the county of Kent, England, have invented certain new anduseful Improvements in Drying and Heating Apparatus; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

Thisinvention relates to that class of devices used for heating anddrying theinterior walls of buildings.

The invention consists in a portable furnace or heater provided withdeflectors, by means of which the heat from the fire contained in thefurnace can be directed against any portion of the walls and into theangles of a room or building.

It further consists in certain. particulars of construction andcombinations of parts, that will be fully described in the ensuingspecification and particularly set forth in the claims at the closethereof.

For a full understanding of my invention I will proceed to describe theconstruction and operation of my improved heating and. drying apparatusas represented in the accompanying drawings, wherein Figure 1 is aperspective view, showing the deflectors in position. Fig. 2 is an endelevation of the same. Fig. 3 is an end elevation, showing thefurnace-walls extended up to form a hood at the top. Figs. 4 to 6 aredetails. Fig. 7 is an end view of the furnace, representing amodification of the form of hood shown in Fig. 3, only so much of thefurnace and dofiectors being shown, however, as is necessary toillustrate the modification.

The same letters of reference are used in all the figures to designateidentical parts.

On a stout frame, A, provided with suitable casters or sledges, a, ismounted a furnace, B, having the necessary grate, ash-pan, drafts, &c.,and beneath the ash-pan I arrange ashallow vessel, 0, which is to bepartially filled with water to'prevent undue heating of the floor of thebuilding in which my drying-furnace is in operation.

I make my furnace B rectangular in crosssection,providing perforationsin the frontand rear vertical walls, I) and b, to permit the heat fromthe fire to escape more freely at these points. The end walls, 11 of thefurnace are made of unperforated metal. Thefurnace is preferablyprovided interiorly with a fire-pot or basket to protect the sheet-metalwalls thereof from the fire.

At the top of the front and rear. walls, I) b, of the furnace I attachby means of binge joints deflectors D and E, of sheet metal or othersuitable materi al, to direct the heat issuing from said front and rearwalls against the walls of a room or building. These deflectors D and Eare held in position after being raised or lowered to the proper anglebymeans of the hooked ends of rods d and c. engaging one of the loops (1or e on the upper sides of the respective deflectors.

I prefer to. makethe deflectors in two or more sec'tions, adjustable oneupon the other, in order to meet the requirements in drying the walls indiiferent sized apartments or buildings, a larger deflector beingrequired in rooms having high ceilings.

The deflectors may be so constructed that when adjusted to theirsmallest size they may be folded down to cover the perforated sides I)and Z) of the furnace. This would be desirable when drying only one ofthe walls of an apartment at a time, as underv these circumstances it isimportant that nearly all the heat from the fire should be radiated fromone side of the furnace. In some instances I prefer to attain this endby securing aremovable plate or shutter against the perforated side I)or b opposite from that at which the drying operation is being carriedon. The sectionsof the deflectors may be made detachable for purposes oftransportation or storage.

To the bottoms of the front and rear walls of the furnace I hingeadditional deflectors, F and G, to be used in conjunction with thedeflectors D and E in directing the heated air from the furnace againstthe walls to be dried. These deflectors F and G may be adjustablysupported from fixed studs on the furnace by means of rods or chains fg,or they'may be supported by rods extending from the floor of the room-tothe under side of the deflectors.

It may in some instances be found desirable to direct the heat radiatedfrom the furnace to a comparatively limited space upon a wall. Toaccomplish this I suspend curtains H from the edges of the upperdeflectors, D E, by links it or other suitable means, which curtains mayextend downward to or past the lower deflectors, F G. These curtains Ihave also made in sections, as shown in the drawings, the upper sectionsbeing attached to the edges of the upper deflectors, the next lower onesbeing attached to the lower edges of the first, and so on.

In some instances I propose to form a hood at the top of the furnace byextending the walls I) and Z) upward, the rear one, I), vertieally andthe front one, I), inclined toward and connected to it, as shown in Fig.3. In this form the deflector E should be hinged ator near the top ofthe vertical wall D, and that portion of the wall I) which is above thedeflector D should be unperforated. In using large deflectors I havefound it expedient to link the hooked rods d and e to a stout verticalbar, I, secured at one end of the furnace. I form a rack on this bar I,so that it can be adjusted vertically by means of a pinion, I, the shaftof which is mounted in hearings on a frame secured to or forming part ofthe frame A, which supports the furnace.

It is obvious that various modifications may be madeintheabove-descrihed apparatus without departingfrom the spiritofmyinventionas, for instance, the furnace might have other than arectangular form in horizontal section, or-the hood might be constructedwith the front and rear walls sloping toward each other and one or bothupper deflectors hinged to the top or peak. These variations of form Iwould regard as but mere modifications and within the scope of myinvention.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. In an apparatus for drying the walls of buildings, a furnace havingone of its walls provided with perforations 0r openings, and havingdeflectors hinged one above and one below said openings, substantiallyas before set forth.

2. The combination, substantially as before set forth, of a furnacehaving one or more of its walls provided with openings, the deflectorshinged respectively above and belowsaidopenings and adapted to be set atan angle with the wall or walls, and means for supporting thedeflectors.

3. The combination, substantially as before set forth, of a furnacehaving one or more of its walls provided with openings, the deflectorshinged respectively above and below said openings and adapted to be setat an angle with the wall or walls, means for supporting the deflectors,and the curtains.

4. In a drying apparatus such as described, the combination,substantially as before set forth, of the deflectors, the hooked rods,the vertical bar provided with a rack, and the pin- 10!].

In testimony whereof I at'fix my signature in presence of two witnesses.
